last year I had the stomach bug, but didn't come down with it till like an hour before the game ( too late to find a replacement). I called my partner and asked if he'd do the plate. I told the coaches at the meeting. long story short, we had to stop the game multiple times for me to run to the right field corner and throw up. not a good day. I did my best, but I was very sluggish. I didn't get any argument, probably because they felt sorry for me. It was just a like 12 hour bug- I called the next day and felt fine.
